Question
When carbon dioxide reacts with red hot coke, what will be the product formed?
- Carbon trioxide
- Coke
- Carbon monoxide
- Carbon and oxygen
Hint:
When CO2(g) is passed over red-hot coke it partially gets reduced to CO(g)
The correct answer is: Carbon monoxide
When carbon dioxide reacts with red hot coke, carbon monoxide is formed. Carbon dioxide is partially reduced to carbon monoxide. The balanced chemical equation for this reaction can be written as:
CO2 + C 
2CO
